Bellows

Gimbal Expansion Joint

A gimbal expansion joint can absorb angular deflection in any plane. It consists of two pairs of hinges connected to a common floating ring. Gimbal Expansion joint can consist of a single bellow, where there is no lateral deflection, or two bellows connected by a common connector where it can permit a lateral deflection also. The pairs of hinges, gimbal pin and the gimbal floating rings should be designed to restrain the pressure thrust.
